IMPROVEMENT IN SHUTTLES FOR LOOMS.

The Schedule referred to in these Letters Patent and making part of thesame To whom it may concern.-

Be it known that I, JOSEPH LOF vExDa-HL, of Woon- I socket, in thecounty of Providence and State of Rhode Island, have invented new anduseful Improvements in Shuttles for Looms; and I do hereby declare thatthe following is a full, clear, and exact description thereof, referencebeing bad to the accompanying drawing which makes part of thisspecification, and in which Figures 1 and 2 represent views of myimproved shuttle, with "hollow spindle, with wire therein for holdingthe bobbin or cop, and a device for attaching the spindle to the shuttleand permitting it to turn to receive the bobbin or cop Figure 3, atransverse section of the same;

Figure 4, a view of a second improved device for attaching the spindleto the shuttle and permitting it to turn to receive the bobbin or cop;

Figure 5, transverse section of the same;

Figure 6, a view of the same with the spindle in position for receivingthe bobbin or cop;

Figure 7, a transverse section of the same;

Figure 8, a view of a third improved device for the same purpose; and IFigure 9, another view of the same device.

The object of my invention is to provide a simple, strong, and durableshuttle with spindle that shall firmly hold the bobbin or cop when inoperation, and afiord ready means for the attachment and removal of thesame, and a shuttle that shall be economical in its construction.

My improvements consist in constructing a shuttle of a frame of sheetmetals, in two or more pieces bent to the requisite form, and united attheir ends by pointed metallic shafts or rods, and provided with eye-'lets through which the yarn is led ofi. Also, devices for firmly holdingthe spindle when the shuttleis in operation, and for permitting it toturn to receive the bobbin or cop, in manner hereafter described.

In the accompanying drawing which shows a convenient arrangement ofparts for accomplishing the objects of my invention, iii-figs. l and 2-A A represent pieces of sheet-metal arranged in rectangular form, outand bent to present a smooth and circular surface on the outside, and tomeet at their ends, where they are united bybrazing, riveting, or othersuitable manner, to poi ntcd steel rods 0 and O.

The part D is made of steel, so constructed as to make a. spring withconcave jaws, E E, and attached to the rod 0 by a pin or other suitabledevice.

The spindle B is attached to the piece F, which plays in the jaws E E byturning on a pivot through these jaws. The spindle B and the piece F maybe constructcd of one piece, and operate in the same manner.

The mode of operation is this: When the shuttle is in operation thespindle l! is held firmly between the jaws E E,.and the removal orattachment of the bobbin or cop is accomplished by pulling the spindle Boutward, which causes the piece F to force open the jaws E E, thuspermitting the spindle to turn on its pivot until thebobbin or cop canbe removed or attached.

The spindle B may be hollow, and in it placed a wire, G, one end ofwhich is fastened in the end of the spindle B, next to the jaws E E, andthe other end loose, thus permitting it to play in the spindle.

The wire G is designed to hold the bobbin or cop on the spindle B bygiving or springing enough to admit the bobbin or cop on the spindle,but no more, and thus, by always springing and pressing against thebobbin or cop, it will hold them firmly on.

H H are eyelets through which which the yarn is led off.

In fig. 4 the shaft may form part of the shuttle and be pointed as infigs. 1 and 2. One end of this shaft (not pointed) is larger in diameterthan the other end.

Through the larger end is a slot entirely through it, as shown at Aroundthe smaller part of the shaft 0 is a core or spring, F, of wire or otherma terial, which is fastened to the barrel or shaft A.

Around the shaft 0 and the spring F is a hollow shaft or barrel, A,which is unconnected with any parts but the spring F, as beforementioned, and can, therefore, be turned around in any direction. It isprovided with a slot through the end next to the spindle, of the samesize as the one in shaft O When it is desired to remove or attach thebobbin or cop, it is only necessary to turn the barrel A until the slotin it comes exactly opposite the one in shaft 0, (in which the spindle Bturns on a pivot,) and the spindle can then be turned through both theslots, as shown in (i.

Having placed the bobbin or cop on the spindle B,

turn it back until it is in its proper place in the shut:

tle, and the spring F 'will then turn the barrel A back again until thetwo slots in. A C are not, opposite, and the spindle B will be firmlyheldby the shaft 0* and thc barrel A.

In figs. 8 and 9- D consists of a spring of steel; exactly as in figs. 1and 2, before described. The spindle B extends through and beyond thejaws E E.

Another spring of steel, I, is placed within the spring I), with jaws JJ,which press upon the end of spindle B, between them, thus holding thespindle more firmly in position when in operation than would be done bythe spring D alone, and yet permitting it to turn readily to receive thecop.

From the construction of my shuttle, it will be seen that it is strong,light, and durable; also, the flexibility of the sheet met-alpermits theshuttle to mid (time.

easily yield, without injury, to any pressure that may come upon it.

My. shuttle is constructed in the form of an open frame, with parallelsides, and permits the spindle to turn outward in either-direction, thusenabling the operative to apply-the .cop without being obliged in anyinstance to turn the shuttle over. It also has eyelets on two sides,through either of which the yarn may be delivered, thus rendering itmore convenient in threading. 4

It, will be observed that my shuttle may rest on either side when inoperation, and is therefore more durable.

The hollow spindle with wire therein readily perinits the reception ofthe cop or bobbin, and firmly holds it on when in operation.

The several devices for permitting the spindle to turn to remove orattach the cop or bobbin, and to hold the spindle firmly when inoperation, are simple, durable, and easy of operation.

Havin thus fully described my invention,
